Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this research is to compare the efficacy and safety between endobronchial silicone valve and endobronchial valve in bronchoscopic lung volume reduction in patients with severe emphysema.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The Cardiotech medical technology CO., LTD Endobronchial Silicone Valve (ESV) is a novel designed implantable bronchial valve intended to decrease volume in targeted regions of the lung. It is indicated for the treatment of patients with severe emphysema. The ESV are placed in the diseased region of the lung using bronchoscopy. Bronchoscopy is a way to access the lungs using a small tube with a camera on the end. As the diseased region of the lung shrinks in size, healthier regions may expand and function more efficiently, resulting in improved breathing.

This clinical trial included two groups. Participants are assigned at random to the 'Treatment' group or to the 'Control' group. The 'Treatment' group will receive the Cardiotech medical technology CO., LTD Endobronchial Silicone Valve (ESV) with optimal medical therapy. The 'Control' group will receive Zephyr Endobronchial Valve (EBV) in combination with optimal medical therapy. For every three participants in the study, two will go into the 'Treatment' group and one will go into the 'Control' group.

It is hypothesized that the ESV has similar efficacy and safety to EBV in treating patients with severe emphysema.
